tpm: eventlog: Fix section mismatch for DEBUG_SECTION_MISMATCH

If DEBUG_SECTION_MISMATCH enabled, __calc_tpm2_event_size() will not be
inlined, this cause section mismatch like this:

WARNING: modpost: vmlinux.o(.text.unlikely+0xe30c): Section mismatch in reference from the variable L0 to the function .init.text:early_ioremap()
The function L0() references
the function __init early_memremap().
This is often because L0 lacks a __init
annotation or the annotation of early_ioremap is wrong.

Fix it by using __always_inline instead of inline for the called-once
function __calc_tpm2_event_size().
